Subject: [PATCH] chore(relay-staging): declare staging C4 on image E so the
 director can deploy it (#27462)

The staging director deploy binds its digest to staging-gce-c4's checked-in image. E is main
2bdb55350d3 (#27405 event-loop max, #27406 sidecar), already mirrored to staging. C4 itself
changes only through its own reviewed refresh workflow.
